. l///// j I UNITED sTATEs PATENT OFFICE JONATHAN HARRIS, OF CLEVELAND, OHIO, ASSIGNOR, BY MESNE ASSIGN- I MENTS, TO BUCKEYE FENCE MACHINE COMPANY, OF ASHTABULA,

OHIO.

WIRE-FENCE-MAKING MACHINE Ohio, have invented certain new and useful Improvements in Wire-Fence-Making May chilies, of which I hereby declare the following to be a full, clear, and exact description,

such as will enable others skilled in the art The specific objects are to provide means for feeding the staples from which the dies f are formed singly, and to prevent the application of more than one staple at `a time thereto, and in the dies to provide means for temporarily retaining the staple under vpressure therein until the die which bends the free extremities of the staple over one of the crossing fence-wires can complete its work.

. The invention consists in the various forms of the dies and die-operating mechanism with the feed mechanism and details of construction and combination and arrangement of parts, as hereinafter described, shown dies.

- dies are mounted, and the upper cross-bar on which the u perdies are mounted, showing also a side elevation of oneof the blades for storing staples and from which they are fed by gravity. Fig. 2 is a transverse section of u per and lower dies,` showing a portion of t e trough which carries thefstaples to the The staple is also seen in position in the lower dies readyl for the impact of the uper dies. Fig. 3 is an elevation of the inner ace of the stationary upper die, showing the Specication of Letters Patent.

wedge shape of the lower die over which the upper die saddles to bend the extremities of the staple about the stay-wire. Fig.- 4 is a plan view of the lower die. Fig. 5 is a side elevation of the upper end of the stapleblade on which the staples are stored. Fig. 6 is a plan view of the same, showing trigger mechanism for releasing one staple at a time 1 and Fig. 7 is a detail view of the device for lowering the staple-blade to prevent the delivery of more than one staple at a time to the lfeed-trough. Fig. 8 is a perspective view of one of the staplesfastened upon the crossing- Wires. Fig. 9 is a detail view of the sta le.

In the views, l is the frame of the mac ne. 2 is the upper cross-bar secured thereto.

Iupon which are secured the die and trou hi base 4, upon which are secured the doub yj grooved die 5 and wedge-die 6, and integral f with the base is the inclined feed-trough 7, which is perforated at 8 for the passage of the I line-wire 9.

iirst stored upon an inverted-T-shaped metal vblade 10, which is pivoted upon the upper j, end of the trough at 1l and thence pass one at a time to the trough and thence to the dies. The mechanism which is arranged to feed one staple only at a time to the trough is seen to consist of the wire spring at 12, one end of Iwhich is forced transversely across the line l of passage of the staples by means of the cam l 13 upon a rod 14. This wire serves as a detent yto hold one staple back in the trough ung til the blade 10, carrying the remaining stai ples, is lowered to the horizontal position, 1 when of course the staples thereon can no longer fall by gravity into the trough. At g this moment the cam 13 is turned to release the spring, which flies out of the path of thel staple in the trough, and hence permits it tofall into the lower die, as shown in Fig. 2. The blade then rises again, and the spring 12 is again passed in front of the staples, so that l the staple next to the spring lies in the trough i ready to fall as soon as released. v

seen to consist of the rock-bar 14', having aI flat surface 15, upon which the vblade restsf .when down, and an edge 16, on which the blade rests when up. The bar 14 is oscillated ton pivotal points -17 in the frame by means trough and lower pivoted end of the staple- 3 is the vertically-reciprocating cross-head,

The staples in theform shown inFig..9 are l IOO The operating mechanism for the blade is of rock-arm 18, link 19, sliding bar 20, and cam-wheel 2l in the main shaft S. The mechanism which operates the cam-rod 14 and compresses the spring l2 is seen to consist of rock-arm and link 22 and 23, sliding bar 24, and cam 25 on the main shaft. The lower end of the blade 10 is curved at 26, so that the last staple will fall into the trough, where it is held until the spring-detent is released. The upper die is divided. One portion 27 is vertically yieldable and is under heavy pressure from a spring 28 above in the die-head 29. This die is recessed at 30 to receive the looped end of the staple, as shown in Fig. 2, and holds it firmly in place as the lower die rises, and the ends of the staple come into contact with the transverse grooves 31 and 32 in the bending-die 33, which is rigidly secured in the die-head and is immovable.

The ends of the staple are oppositely beveled off at and y, so that they can readily pass one another. The upper bending-die is doubly and transversely grooved to engage these ends and bend them down about the line-wire 9, one groove engaging one end and the other groove the other end and forcing the ends past one another, while the line-wire is supported upon the wedge-shaped portion of the lower die.

The lower die is provided with longitudinal grooves 5, which receive the curved sides of the staple, while the yielding upper die 27 engages the looped portion of the staple.

A spring-pressed sliding keeper 36 is provided with a forked point 37, which as the lower die rises engages the rear of the staple and keeps it in position while the lower die rises. A spring 38 serves to maintain the contact of the keeper with the die.

I-Iaving described the invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a machine for making wire fence, the combination with yielding and stationary upper dies, and vertically-reciprocating lower dies, of a staple-feeding trough adjacent to the lower dies, a staple-carrying blade pivoted to the outer end of the said trough, having staples thereon, a spring-detent in the trough at the upper end, and means for lowering said blade and for thereafter releasing said detent to permit one staple to fall into the lower die, substantially as described.

6. The combination with the lower dies of a staple-attaching device for wire fencing,'of a trough leading to said dies, a staple-storage blade pivoted to the upper end thereof, a spring-detent at the upper end of said trough, adapted to retain a staple discharged into said trough from said. blade, means for releasing said detent, consisting of a rotatable cam adjacent thereto, and means for lowering said blade to prevent the staples thereon from passing into said trough when the detent is released, and for elevating the blade to provide another staple for the trough, substantially as described.

7. In a machine for the purpose described, an upper die one portion of which is yielding and the other portion fixed, a vertically-reciprocating lower die, a transverse bar in which said lower die is fixed, a main shaft and cam thereon engaging said transverse bar, and a staple-feed device comprising a trough communicating with the lower die at its lower end, a staple-storage blade pivoted to said trough and discharging therein, a detent in thelupper end of the trough adapted to retain al staple from the said blade, means for withdrawing said detent to release said staple and for replacing the same, means for lowering said blade to prevent the discharge of the staples thereon until said detent is replaced, and cams upon said main shaft, and mechanism controlled thereby for Operating said blade and detent, substantially as described.
